Emily Mohsenian followed her doctor's recommendation -- waiting until her son Owen was five moths-old to give him solid foods.
"He seemed ready. He was able to sit nicely in a chair, hold his up straight and he was showing interest in what his brothers were eating so we thought it was a good time to start," Mohsenian said.
Pediatrician's recommend introducing solids no earlier than 4 to 6 months old when a baby's body is developmentally ready. But a new study published in the journal Pediatrics finds 40 percent of mothers are not waiting.
"Often starting solids less than four months of age can increase the risk of certain chronic illnesses such as celiac disease, obesity -- diabetes even -- eczema and dry skin'" said pediatrician Dr. Elissa Rubin.
The study looked at about 1,300 moms. nine percent started solids as early as four weeks. Mothers who introduced solid foods early believed their babies were old enough to start. They also thought it would help their babies sleep longer at night.
Owen's mom is having success with solids while she continues to breast feed. "I'm just kinda fitting in solids in between the feedings once or twice a day," she said -- so far, carrots are his favorite.
